We recently published a list of 12 Most Expensive Stocks Insiders Are Buying After Trump’s Tariff Rollout. In this article, we are going to take a look at where WD-40 Company (NASDAQ:WDFC) stands against other most expensive stocks insiders are buying after Trump’s tariff rollout.
Wall Street banks have sharply cut their targets for the broader market index due to growing fears about the economic fallout from new tariffs, writes the Financial Times. Since the tariff announcement on April 2, the broader market index has dropped nearly 7%. Major banks now expect lower market gains in 2025, with some analysts predicting a possible bear market directly triggered by presidential policy shifts.
Amid tariff wars and market uncertainty, insider trading often draws attention. Insider stock purchases may signal executive confidence, while sales aren’t necessarily negative—they could reflect personal or diversification choices. It’s best to view insider trading in context with a company’s financials and market conditions.
