The Anatomy of a Tesla ($TSLA) Trader Analyst
Hi, my name is …
Marco Papa. I am a techie by trade and very much a product of the first dot com boom (and bust) of the 90’s. I originally came to this country from Italy to pursue a PhD in computer science at USC, back in 1981. I worked for 6 different dot-coms in the span of 10 years, starting as software developer, then system architect all the way to several CTO positions. All these companies, except one, no longer exist: they either were sold, or went bankrupt. But in the process I learned a lot about company valuations, private placements, and raising tens of millions of dollars from VCs, banks and brokerage houses. And yes, like many other Internet executives of the time, I owned a Ferrari 355 spider convertible. I’ll come back later to the Ferrari.
After 10 years of high-stress jobs, I decided to move to slower-paced “environments”: for the past 14 years I have held a daytime job working for state government and a nighttime job teaching Web Technologies at USC.
“Buy what you know”
But it is during the dot-com era that I started tinkering with Mutual Funds and stocks. For the initial 15 years I was an “investor”. I would purchase mutual funds and stocks and hold them for a minimum of a year. Then in 2005 something changed: I consolidated all my retirement funds from the various companies I had worked for into a single SEP-IRA at E-Trade and strangely enough, after answering a simple questionnaire, E-Trade gave me access to Level 2 Options trading. I did not know much about options then, so I subscribed to a service called the Options Oracle from The Market Guys (http://www.themarketguys.com), which recommends entry and exit points for options trades for a fee. I learned a lot, but I felt frustrated that I was trading options of companies I knew nothing about. So I decided to follow an investment method that I had learned when I used to hold shares in Fidelity Magellan Fund (https://en.wikipedia.org/wiki/Magellan_Fund), a fund with $20B of stock investments, and the best performing one between 1977 and 1990, averaging over a 29% annual return. Peter Lynch, Magellan fund manager at that time, created the investment method commonly referred to as “Buy What You Know”: invest in businesses that you understand “personally”, especially if you buy and own their products. Since that time, I have tried to follow the “Buy What You Know” method in all my investments and trades.
Interestingly it is at that time that I started making my “switch” from Windows to the Mac. My first Apple purchase was an iPod; I subsequently trashed a ThinkPad and bought a MacBook, and finally trashed an HP desktop and bought a Mac Pro. Today I own probably close to 25 Apple devices, once I count all the iPhones, iPads, Apple Extremes, Apple TVs, and Apple Watches my wife and I use daily. In 2006 I started “investing” in Apple stock. After the stock market crash of 2007, I started “trading” Apple options. Between 2006 and 2014 I made more money trading AAPL than any other stock. During that time, I added a few more stocks to my trading pattern: Netflix (NFLX), Amazon (AMZN), Google (GOOG), Facebook (FB), Starbucks (SBUX) and more recently Tesla Motors (TSLA). These are all companies that qualify for the “Buy What You Know” mantra: I either buy their products regularly or use them in my daily life.
$TSLA to P90D
I started reading about Elon Musk since he founded PayPal. I read about his promotion of sustainable energy as a way to save our planet. In 2012 I installed solar panels in my house in Redondo Beach, CA. In 2013 I replaced my energy-hog 2007-vintage Mac Pro with a low-energy Mac Pro (a.k.a. the “can”). In 2014 I switched all light bulbs in my house (over 300 of them) from incandescent to low-energy LEDs. And in 2015 I bought a red Tesla Model S P90D (a.k.a. Red Five X-wing). By now my carbon footprint is in pretty good shape.
I started trading TSLA options in early 2014. By summer of 2015 I had enough profits from option trades in TSLA, AAPL and SCO to pay in cash 2/3 of the price of my P90D.
After trading TSLA for over two years I have a few opinions on how to invest or trade it. A stock for me is a good “investment” if it can be held for about 5 years, and provide annual stock gains of 5-10% per year. If you had purchased TSLA stock at the IPO in 2010 at about $19, you would be sitting pretty at a 10-bagger at $250, 6 years later. But if you had purchased it in March 2014 at $265 you’d be about even, two years later. Twice in the past couple of years TSLA stock raised to $275, while slamming back to $140-180 in just 6 months, both times. Tesla in my opinion is not yet a good long term investment.
Part of the reasons is that good long term investments are based on “fundamental” analysis of stocks. Fundamental analysis is based on analyzing the characteristics of a company in order to estimate its “value:” high earnings, income, high profit margins, and small debt are what investors are looking for. According to a recent thestreet.com article, “Tesla Motors has a ‘sell’ rating and a letter grade of D+ at TheStreet Ratings because of the company’s deteriorating net income, generally high debt management risk, disappointing return on equity, poor profit margins and feeble earnings per share growth.”
So if I would not recommend TSLA stock as an investment, why would I even consider TSLA for my trades? Because TSLA is a wonderful stock to trade, not on the basis of “fundamental” analysis, but on the basis of “technical” analysis. In finance, technical analysis is a security analysis methodology for forecasting the direction of prices through the study of past market data, primarily price and volume. The “value” of the company does not matter. Even just 10 years ago, trading on the basis of technical analysis was only for the pros: brokerage houses, money managers and hedge fund managers. Today individuals have access to tools, indicators, and “conditional” trades that make trading, and especially options trading, much easier and safer.
I consider myself a “swing” trader: I normally enter an option trade when at least 3 indicators are firing on all cylinders; I put conditional stops to lower my losses when the market goes against my trade, and get out of trades when indicators are turning negative.
Coming up
It turns out that TSLA is a fairly good “swing” stock, where the above methodology has worked well in the past. In the next few weeks, while covering the news about the company that can affect its stock price, I will introduce some of the tools, indicators and techniques that any trader can use to profit on TSLA. You’ll hear names like moving averages, pay-day cycles, MACD indicator, Heikin-Ashi charts, support and resistance lines. You will see that none of these are rocket science.
I will write a column, a couple of times a week, providing TSLA stock analysis, information on investing and trading TSLA stock and options, and covering TSLA earnings and all rumors and news that can affect the stock.
Now back to the Ferrari. The F355 Spider that I purchased in 1996 was priced at $137,000, had a top speed of 183mph, 375hp, 268lb-ft torque, and performed 0-60mph in 4.5s and the quarter mile in 12.9s.
The Tesla Model S P90D (Insane) I purchased in 2015 has a very similar price, $142,000, but with a top speed of 155mph, 691hp, 713lb-ft torque, and performs 0-60mph in 3.1s and the quarter mile in 11.7s. The Tesla sedan beats the Ferrari in all but the top speed rating.
But while you needed a Formula 1 driver to obtain those numbers in the Ferrari, mainly to change the gears at the exact right time, effectively anyone can get the Tesla numbers just by flooring the accelerator. The only thing I miss from the Ferrari is the “roar” of the engine; for everything else the Tesla is so much more fun.
Disclosure: I currently have no positions in any stocks mentioned, but I may plan to initiate positions within the next 72 hours. I wrote this article myself, and it expresses my own opinions. I am not receiving compensation for it (other than from Teslarati). I have no business relationship with any company whose stock is mentioned in this article.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn
— Elon Musk (@elonmusk) July 21, 2026
The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
In a pointed message on X, Elon Musk warned that firms maintaining significant short positions in SpaceX over time face “very low” survival probability.
The statement comes amid post-IPO volatility for the rocket company, now trading under the ticker $SPCX.

Five weeks after what was described as the largest IPO in history, the stock had fallen roughly 30% from its peak above $2.6 trillion, briefly surpassing Microsoft and Amazon in market value. Short sellers celebrated gains of about $8.7 billion, but Musk’s reply underscores his long-term conviction.
The warning directly echoes a detailed bullish analysis arguing that Starship’s cost reductions could unlock a multi-trillion-dollar space economy. Projects ranging from solar power beamed from orbit and asteroid mining to orbital data centers and Mars terraforming were projected to create over $100 trillion in new market capitalization.
In this vision, SpaceX acts as the essential infrastructure provider, akin to AWS for cloud computing, capturing monopoly-like revenues from launches, crew transport, and data traffic across a rapidly expanding frontier.
This is far from the first time Musk has targeted short sellers. With Tesla, he has repeatedly framed persistent bears as destined for major losses. In July 2024, Musk declared that once Tesla achieves full autonomy and volume production of Optimus robots, “anyone still holding a short position will be obliterated. Even Gates,” referencing Microsoft co-founder Bill Gates’ reported short bets.

Earlier, in 2018, he taunted shorts that they had “about three weeks before their short position explodes,” a remark followed by sharp stock gains. Musk has also called short selling “value destroying” and once suggested it “should be illegal,” viewing it as betting against innovation and progress.
Critics often dismiss Musk’s optimism as hype, especially when near-term metrics like quarterly deliveries or stock fluctuations disappoint.
Yet his pattern remains consistent: framing short positions against his companies as fundamentally misjudging exponential technological leaps. For SpaceX shorts, the message is clear: betting against multi-planetary ambitions and the infrastructure monopoly they enable carries existential risk for the firms involved.
As Musk and supporters see it, the space economy’s upside dwarfs Earth-bound valuation models, making today’s dips temporary in a decades-long ascent.

SpaceX Starship Flight 13 aborted at Zero and Musk just told us what broke
Four Raptor engines failed to ignite at T-zero, forcing SpaceX to scrub Starship Flight 13 Thursday.
SpaceX scrubbed the Starship Flight 13 launch attempt Thursday evening at the last possible moment, after four of the Super Heavy booster’s 33 Raptor 3 engines failed to ignite during the startup sequence. The 90-minute window had opened at 6:45 p.m. EDT from Starbase in Boca Chica, Texas, and the countdown had proceeded without issue all day, with more than 11.5 million pounds of liquid methane and liquid oxygen being fully loaded into the rocket before the automated abort triggered. SpaceX’s launch directors posted on X, “Standing down from today’s flight test attempt,” and shut down the livestream shortly after.
Musk confirmed the root cause within hours. “Some of the engines didn’t start, triggering an automatic launch abort,” he wrote on X. “To be confident of a good flight, 2 Raptors will be removed and replaced. Most probable launch timing is early next week.” SpaceX engineers began draining propellant tanks immediately and Booster 20 was rolled back to its hangar for inspection.
The timing adds a layer of significance that did not exist during any of the previous 12 Starship flights. This is the first time SpaceX has attempted to launch Starship since the company made its stock market debut in June, listing under ticker SPCX at $135 per share. Public investors are now watching every Starship outcome in real time, and a last-second abort carries more visibility than it would have six months ago.
Flight 13 was designed to be one of the most consequential tests in the program’s history. It was set to carry 20 Starlink V3 satellites, the first operational payload Starship has ever attempted to deploy. Six of those satellites carried external cameras to photograph Starship’s heat shield from the outside during flight, which would act as a self-inspection approach SpaceX has never attempted before. The mission also needed to complete a Raptor engine relight in space, a step SpaceX skipped on Flight 12 in May after losing an engine during ascent. That Flight 12 booster also flipped 90 degrees off course during its boostback burn when five engines failed to reignite.
SpaceX has not announced an official next launch date. Musk’s “early next week” window points to July 21 or 22 at the earliest, pending the engine swap and a return to the pad.
