Tesla is the most-discussed stock in retail investing, and it’s also one of the most reliable places for retail investors to lose money, usually by doing something that felt sensible at the time. This isn’t a bull or bear case on the company. It’s a look at five specific mistakes I see repeated around this stock, quarter after quarter, with the numbers from the last few months attached, and what a more disciplined version of each decision looks like.
Mistake 1: buying far out-of-the-money calls as cheap lottery tickets
Tesla’s options chain is a clear window into retail behavior, and it isn’t flattering. Roughly 41% of outstanding call open interest sits more than 65% out of the money. People buy those contracts because the premium looks cheap, without doing the second calculation: how far, and how fast, the stock has to move for the trade to work.
The market itself is telling you these are tail bets. Tesla’s December-dated options are pricing something like a 37% chance of a large move up and a 31% chance of a large move down. That much implied volatility means the “cheap” option isn’t actually cheap relative to its odds of paying off. A call struck 65% above spot isn’t a modest bullish position. It’s a lottery ticket on an event the market considers unlikely, bought over and over, most of them expiring worthless. If you want directional exposure through options, staying closer to the money gives you a breakeven that’s at least reachable. Run the trade through an options profit calculator before you put money on it, and you’ll usually talk yourself out of the far-OTM version.
Mistake 2: panic-selling the one-day crash and missing the bounce
On July 23, Tesla dropped 14.5% in a single session, its worst day of the year, after a shareholder deck framed the road ahead as the company’s “largest and most exciting period of investment.” Markets wanted spending discipline; they got a growth pitch, and the selling was fast. The stock bottomed at a 52-week low of $298.32 within about six sessions.
Then it rallied 21.6%, closing at $362.86 on August 21. The business that supported the stock before July 23 was the same business afterward. What changed was sentiment, and then sentiment changed back. Investors who sold near the $298 low locked in the loss and sat out the recovery, which came with no new catalyst attached. The core error is treating a single-day crash as fresh information about the company rather than a prompt to check whether the earnings power actually moved. With a stock that produces double-digit daily swings as often as Tesla does, that reflex is a recurring, self-inflicted wound.
Mistake 3: cheering the delivery headline and ignoring the multiple
Q2 2026 deliveries of 480,126 vehicles were a record, up 25% year over year, and that number dominated the retail coverage. Revenue of $28.24 billion beat consensus by about 7%. On the surface, good news.
| The headline | What was underneath it |
|---|---|
| Record 480,126 deliveries, +25% YoY | Operating margin of 1.4%, down from 4.1% a year earlier |
| Revenue $28.24B, ~7% above consensus | Free cash flow of −$1.09B; capex up 142% to $5.79B |
| EPS $0.33, beating estimates by ~38% | Trailing-12-month EPS of $1.08 → a P/E near 336 |
A record delivery quarter run at a 1.4% operating margin with negative free cash flow is a fundamentally different event from a record quarter with expanding profitability, even though the headline reads the same. The margin drop reflected pricing pressure, heavy AI-infrastructure spending, and costs tied to the 2025 CEO performance award. If you only track units and revenue, you miss the part of the report that decides whether the valuation makes any sense. Even at a hypothetical $250 share price, the trailing P/E would still be north of 230.
Mistake 4: using leveraged ETFs to “amplify conviction”
Daily-reset leveraged products, the 1.5x and 2x long funds and their inverse versions, see heavy retail volume around Tesla, and the appeal is obvious: if you’re right about direction, why not multiply the payoff? The problem is the same one that applies to every daily-reset product on a volatile underlying. The leverage resets against yesterday’s price, not your entry, so a sharp drop followed by a recovery to the same level leaves the leveraged wrapper below where it started. This decay compounds with volatility, and Tesla is close to a worst case for it: a 14.5% single-day drop, a new 52-week low, then a 21.6% bounce is exactly the path that erodes a leveraged position even if the stock round-trips to breakeven. These instruments are built for one-day tactical use. Held for weeks, they rarely deliver the clean multiple holders expect.
Mistake 5: treating every headline as equally important
Tesla generates an enormous volume of news, and most investors have no filter for which items actually move long-term value.
Take one week in late August. Nevada approved Tesla, along with Uber and Waymo, to run up to 5,000 fully autonomous robotaxis in Las Vegas, and the stock jumped more than 5% that day. In the same week, Tesla quietly wound down its Solar Roof business after years of development, a real strategic retreat from a product it had repeatedly promised as a growth line, and the market barely reacted. The robotaxi approval was treated as the story of the week because it was the loudest, not because anyone had weighed it against its likely contribution to earnings. That’s the pattern: a stock trading heavily on narrative, at a multiple its current earnings can’t support, rewards patience and multi-factor judgment and punishes trading on whatever is trending.
What a disciplined approach looks like
None of this makes Tesla uninvestable. First-half 2026 diluted EPS of $0.45 was flat against $0.45 in the first half of 2025. After earnings fell roughly 75% over two years, from $4.30 in FY2023 to $1.08 in FY2025, flat is a genuine inflection. The decline has stopped. It hasn’t turned into growth yet. That distinction gets lost in the noise from both the bulls and the bears.
Every one of the five mistakes shares a structure: acting on a single vivid data point (a cheap-looking premium, a scary crash, a record delivery number, the pull of leverage, an exciting approval) without checking it against the numbers sitting right next to it. Tesla, with its combination of extreme volatility, a very high multiple, and constant news flow, is the stock that penalizes that habit most consistently. It’s also, for the same reasons, one of the best training grounds for breaking it. The comparison with SpaceX is worth reading if you want the longer-term framing.
