Did Susan Collins Beat the Stock Market? | Politician Stock Tracker

Did Susan Collins beat the stock market? On the stock purchases she has disclosed since mid-2016, our answer is no—at least in this window. Those buys returned about 136%. Buying the S&P 500 with the same money on the same days returned about 205%. She made money in absolute terms in many cases—but still trailed simply matching the index. That is a narrow lens on STOCK Act disclosures—not her entire wealth.

The short answer

Question	What our data shows
Did disclosed buys beat the S&P 500?	No — about 136% vs 205%
How many buys?	25 purchases we could price since mid-2016
Did she pick great days to trade?	Below a coin flip — about 46% vs a 50% luck baseline

Beating the market on what she bought and beating it on when she traded are different questions.

How we compare her to the market

Imagine this: every time Collins disclosed a stock purchase, you bought the same amount of the S&P 500 (through SPY, a fund that tracks the index) on that same day. Then you compare the two paths.

Collins's disclosed buys: about 136%
S&P 500 on the same dates: about 205%

Her most-disclosed names include PYPL, SYK, HOLX, TSCO, AMZN, COP. Overall disclosure volume is large, but the priced-buy sample used for returns is smaller than for the busiest House traders.

Limits to keep in mind: disclosure forms report dollar ranges, not exact share counts. This measure covers disclosed stock purchases only—not every asset class. Full details live on her Susan Collins stock tracker page.

Timing is a separate question

Some people hear "beat the market" and mean "she knew the perfect day to buy." That is trade timing—and we measure it separately.

50% is roughly what random luck looks like. Collins's overall score sits around 46%:

Measure	Score	vs 50% luck
Overall	46%	-4 points
Buys	40%	-10 points
Sells	52%	+2 points

With medium confidence and 67 scored trades across 50 stocks, treat this as no timing superpower—and possibly worse than random.
