Alphabet, Rheinmetall, Alstom Fall on Crowded Trades

Alphabet is the clearest example in the data. The stock fell to $288.15 on Nov. 9 from $382.50 in May, a decline of about 25%, after briefly touching $288.93 a few days earlier. The selloff has pushed the shares below their 200-day moving average of $339.02 and left the 14-day RSI at 23.8, a level that indicates the stock is deeply oversold on a technical basis. The MACD remains sharply negative, another sign that momentum has turned decisively lower.

That matters because Alphabet is widely held as a core large-cap technology position, so a drop of that magnitude can reverberate through passive and active portfolios alike. The move also underscores how sensitive mega-cap tech has become to shifts in rate expectations, AI spending concerns and evidence of slowing near-term earnings momentum. When a stock of Alphabet’s size loses a quarter of its value in months, it is rarely just about one quarter’s numbers; it often reflects investors revising how much future growth they are willing to pay for.

The pattern is even starker in Europe. Rheinmetall has fallen to 812.7 euros from 1,811.89 euros in late January, a drop of more than 55%, with the shares now well below both the 50-day and 200-day moving averages. Its RSI near 16 suggests capitulation-like selling. Alstom has been cut to 10.72 euros from 29.8 euros in February, a loss of about 64%, with the stock also deep under its moving averages and RSI near 10. Both names were previously major beneficiaries of the market’s appetite for defense, infrastructure and reindustrialization plays.

For Rheinmetall, the decline matters beyond the stock chart because it shows that even defense names can be treated as momentum assets when positioning gets crowded. For Alstom, the move reflects a harsher reassessment of execution risk in cyclical industrials, where investors are willing to pay up only while order books and margins look unassailable.

The macro backdrop helps explain why the selloff is spreading now. U.S. 10-year yields have risen to about 4.9%, the two-year note is around 0.32%, and the federal funds rate is close to 3.9%, keeping discount rates elevated even if inflation has eased. Higher real yields tend to compress valuations most sharply in long-duration growth stocks and can also unsettle industrial names if investors start to fear slower global demand. Adalytica’s S&P 500 trade signals show awareness at 99, an “extreme greed” reading, even as sentiment has slipped to neutral, a combination that often accompanies fragile positioning rather than durable risk appetite.

The investment implication is that these slumps are less a verdict on a single sector than a warning about positioning. Bulls can argue that oversold readings on Alphabet, Rheinmetall and Alstom leave room for a sharp bounce if macro conditions stabilize or earnings hold up. Bears will counter that the market is simply stripping out excess optimism after a long period in which investors were willing to pay for every visible growth theme, from AI to defense to rail electrification.

What to watch next is whether the selling stops at technical support or whether earnings revisions start to follow the price action. If rates stay high and growth expectations soften, the next phase could be less about a single rotation and more about a broader de-rating of the market’s most crowded winners.
