$MARA 20261030 11.0 CALL$ Sell covered call again.
$IBIT 20261023 47.0 PUT$ Was supposed to be a pair with the ibit short. Closed that earlier and was anticipating a bigger move tonight. It seems muted tonight. Will close this position since the pairing is not around anymore. 
$COIN 20261030 160.0 PUT$ Cash secured put. Putting a longer duration sell put on it, but placing strike at the lowest point of the "boring" zone.  Refer to earlier post on the different levels I'm looking at for COIN. Will probably do an update again next week.
$MARA 20261030 11.5 CALL$ Selling even more covered calls
$BMNR DIAGONAL 261120/261016 CALL 30.0/CALL 28.0$ Short call almost worthless with 1 week left. Rolling out to a higher strike price hoping to capture more stock gains. Bullish on bmnr and eth for the next 1-2 years. Though the speech from Tom Lee saying they will stop at hard cap of 5% of eth, the bullish momentum will not stop just because he stops buying. End of the day, it will be more important that BMNR manages the treasury of eth properly and maximising shareholder value.
$MARA 20261106 11.5 CALL$ Even more painful than yesterday. Still, sold some covered calls. Sticking to the plan.
$COIN 20261009 172.5 PUT$ The stock climbed too fast. Dont think I can catch it tonight. Close for a small profit 
$ORCL DIAGONAL 261023/261106 CALL 195.0/CALL 180.0$ Rolling the short calls down. Current ones are almost worthless. Trying to squeeze some theta decay from it. Not the best because I cap the up side much more than before.
$COIN 20261009 172.5 PUT$ Selling 2 cash secured put. Increasing position size on coinbase 
$iShares Bitcoin Trust(IBIT)$ Buying back ibit short leg. Keeping the sell put on. 

The Board Is Pricing ±8.9% On Netflix Earnings. The Downside Break-Even Sits Below The 52-Week Low

$Netflix(NFLX)$   Mathematical Money | October 9, 2026 $NFLX$ closed Thursday at $71.57. That's down 23.7% this year, 42.3% below the 52-week high of $124.14, and only 6.7% above a 52-week low of $67.06 that was set on 2 October. Seven days ago. Netflix reports third-quarter results after the close on Tuesday 20 October. I own long-dated calls on it and I had a decision to make before then, so I did what I always do before an event and wrote the number down first. What the options board is actually pricing I captured this on Friday morning, before the event rather than after it. The 23 October expiry, which is the first one that contains the earnings date, has an at-the-money strike of $72. The call was $3.05 at the midpoint and the put

The Dow Is Down 6% Since August. Goldman Sachs Alone Is A Third Of It.

$SPDR Dow Jones Industrial Average ETF Trust(DIA)$   $SPDR S&P 500 ETF Trust(SPY)$   $Invesco QQQ(QQQ)$   Mathematical Money | October 9, 2026 Two things are true at the same time right now and they shouldn't be. $SPY$ and $QQQ$ both set record closes on Tuesday and sit within one percent of them tonight. $DIA$ peaked on 5 August and has fallen about 6% since, with no bounce worth the name in between. Most of the commentary I've read explains this as old economy versus new, or value versus growth. I went and did the arithmetic instead, and the answer turns out to be much more specific than that. A third of the Dow's entire decline i

$MARA 20261023 11.5 CALL$ Painful to sell covered call at this price. But just doing it to collect premium. Again, cant predict when it will spike or go down, just keep doing the same
$COIN DIAGONAL 261023/261106 CALL 190.0/CALL 202.5$ Taking this chance to roll the short call higher. This pull back allowed the short call to be back in profit. The capped at 190 is shifted further to 202.5 Still looking at collecting premium over the next 30 days but with potential for further upside. Hoping the development of various features and guidance during earnings will prove COIN better.  Cant predict. So lets see.
$VST DIAGONAL 261030/280121 CALL 170.0/CALL 125.0$ Taking profit on this final pair.  Not because it has no more room to run, but it arrives much faster than I expected. May still have a bit of room, probably 180-190.  Im looking for something else that may have longer runway.

First Solar Hit A 52-Week Low When An Analyst Cut His Target To 45% Above The Share Price

$First Solar(FSLR)$   Mathematical Money | October 7, 2026 $FSLR$ set a fresh 52-week low on 1 October. The trigger was a Piper Sandler downgrade — they lowered their price target from $260 to $251. Sit with that for a second. The stock made a new annual low because an analyst reduced his target to a level roughly 45% above where the shares were trading. That is what a market looks like when it has stopped listening to targets and started pricing a problem. I bought into it on Monday. Here's the reasoning, including the part that argues against me. The business is not the problem Second quarter, reported at the end of July. Earnings per share of $3.92, up 23% year on year — on revenue that actually fell 4%. That combination only happens
