Which Aerospace and Defense ETF Is the Better Buy: State Street's XAR or First Trust's MISL?

MISL employs market-cap weighting with higher concentration in defense giants and tech companies, offering lower volatility but higher fees (0.6%) and lower returns (9.6%).

Prediction: Palantir Stock Is Going to Plunge on Aug. 4

Palantir Technologies is expected to report strong Q2 earnings on Aug. 3, likely beating Wall Street estimates as it has for 11 consecutive quarters. However, the article argues the stock will plunge on Aug. 4 due to an unsustainable valuation. With a price-to-sales ratio of 61 (down from over 100 at the start of 2026), Palantir remains in bubble territory. Historical precedent shows that companies at the forefront of major technological innovations rarely sustain such high valuations, and AI is unlikely to be an exception. The author predicts no earnings beat will be sufficient to justify the current stock price.

Palantir Technologies has become a divisive stock with strong fundamentals but elevated valuation concerns. The company reported impressive Q1 results with 133% U.S. commercial revenue growth and record profitability, with analyst Param Singh predicting a beat and raise for Q2 earnings.

Famous Investor Michael Burry Is Short Nvidia, Palantir, and Tesla. Why I'd Buy 1 of the Stocks, Hold Another, and Sell the Third.

Michael Burry is short on Nvidia, Palantir, and Tesla, but analyst Geoffrey Seiler disagrees with his bearish stance on all three. Despite Burry's concerns about AI spending slowdowns, Seiler recommends buying Nvidia due to strong capex trends and attractive valuation. Palantir is rated a hold despite high valuations, given its rapid growth and strong net dollar retention. Tesla is recommended as a sell due to loss of regulatory credits, weak auto sales, and execution risks in robotaxi and robotics ventures.
