Financial markets have been volatile since President Donald Trump's election on Nov. 5, 2024, and subsequent inauguration. Which companies have surged under the new administration and which have struggled?

Best Performers: Six companies in the SPDR S&P 500 ETF Trust (SPY  ) have returned over 30% since Nov. 5, 2024, according to data from Benzinga Pro.

Palantir Technologies Inc. (PLTR  ) leads the pack, rocketing up 59.91% from $51.13 to $81.76. The Denver, Colorado-based company's annualized return is over 184%. The retail investor darling has capitalized on AI trends and CEO Alex Karp's support for Elon Musk's government efficiency efforts, which he defended as a push to eliminate fraud, waste, and abuse.

According to Benzinga Edge, the company has momentum on its side, scoring a very high 99 out of 100, though it lags on key valuation metrics, indicating the stock could be overvalued.

Five other stocks have returned 30% or more since Trump's election victory:

• Tapestry Inc (TPR  ), up 49.66% (148.56% annualized).
• Warner Bros Discovery Inc (WBD  ), up 35.32% (105.68% annualized).
• VeriSign, Inc (VRSN  ), up 33.19% (99.30% annualized).
• Super Micro Computer Inc (SMCI  ), up 33.32% (99.69% annualized).
• Gilead Sciences Inc (GILD  ), up 30.48% (91.19% annualized).

Some poor performers have been impacted by Trump's policies. First Solar Inc. (FSLR  ), a manufacturer of solar panels, has seen its stock decline amid concerns about Trump's support for fossil fuels. The Tempe, Arizona-based company's shares have sunk 36.41% since Nov. 5, 2024.

Benzinga Edge indicates the company may be undervalued at depressed valuations but does not fare well with its momentum and growth prospects.

Four other stocks round of the worst performers in the S&P 500 since Trump's win:

• Iron Mountain Inc's (IRM  ) shares declined 34.47%.
• ON Semiconductor Corp's (ON  ) shares fell 35.71%.
• FMC Corp's (FMC  ) shares tumbled 35.32%.
• Celanese Corp's (CE  ) shares sunk 39.6%.
