SanDisk flipped long and short three times; are institutions stepping in to go long again this time?

In the past half month, SanDisk's option flow has been repeatedly volatile, and this is now the third time.

Let's first review the recent two anomalies:

On July 2nd, near the close of trading, a multi-million dollar long-dated LEAPS call appeared in the intraday market, betting that the storage super-cycle will extend into 2027.

By July 6th, Samsung's earnings preview was interpreted as "good news fully priced in," and a large near-term Put was dumped, shifting the capital's perspective to bearish.

In the following days, SanDisk fell from $1750 all the way down to $1354, and that Put position profited handsomely.

Last night, at-the-money Calls at $1600 were swept up six times in one morning, totaling $10.66M, bought almost at the current price. The visible bullish catalysts mainly include: JP Morgan predicting a 25% increase in storage prices next quarter; BlackRock stating that this round of chip sell-off is oversold, specifically naming SanDisk and Micron for acquisition; the underlying stock rebounded in a V-shape from the pit bottom of $1354 back to $1599, and surged to $1628 in pre-market trading.

The structure is very straightforward: $1600 at-the-money Calls, expiring on 8/21, with 30 days to expiration (DTE), averaging about $262.8 per share. The break-even point is $1862.8, requiring another ~16.5% rise from the current price; the maximum loss per contract is the premium paid, approximately $26,300. If it rises, gains are yours; if it falls below, the premium is lost. A small amount of $1505 Buy Puts were also paired during the session as insurance, while the main leg remains those six consecutive large Call sweeps.

I summarize this anomaly as "chasing the V-rebound with at-the-money orders": the current stock price has already recovered significantly from the pit bottom. Buying at-the-money Calls at the halfway point of the rebound, combined with the stampede 行情 driving IV extremely high, means buying time at a high price. If it breaks below the previous low of $1354, this trade is proven false; if it goes up and stabilizes above the pre-market high of $1628, and the data on storage price hikes truly materializes, I would consider continuing to follow the trade. Recently, the storage sector has seen high volatility, and large orders in the option flow are chasing the trend. Although the volume this time is large, I find it hard to believe it is a long-term layout, so I treat it as "taking a short-term swing trade alongside smart money". The turning point for the medium-to-long term still requires more clear positive catalysts.
