While CEO and COO open-market buys are strong signals, their absence isn't fatal. In Fiserv's case, recent buys from the new CFO, Chief Legal Officer, and a director with a history of successful insider trades provide critical, albeit more nuanced, confirmation of a turnaround from key oversight roles.

In biotech, CEO insider buys are common and not very predictive. The real signal comes from the rest of the management team, especially the CFO. CFOs are typically more bearish and financially disciplined, so their decision to buy company stock is a particularly strong vote of confidence.

Despite massive stock price drops, there is a notable lack of significant insider buying at many SaaS companies. This passivity suggests management and boards may not believe a quick recovery is imminent, preferring to wait for an "all clear" signal before deploying their own capital.

Contrary to expectations given the 'SaaS apocalypse', a survey of software employees revealed they want a higher proportion of their compensation in stock, preferring around 35% versus the 25% they currently receive. The lure of life-changing wealth from equity continues to outweigh market volatility.

Analyzing past disruptions (newspapers, tobacco), stock prices didn't recover until downward earnings revisions ceased. For investors in today's AI-threatened software sector, the key buy signal is not a low price but the stabilization of forward earnings estimates, which may take multiple quarters to appear.

Empirical studies show that the strongest investment returns don't come from insider buying or value investing in isolation. The key is the combination: systematically buying stocks that exhibit C-suite insider purchasing and also rank in the cheapest deciles based on quantitative value metrics.

Warren Buffett's successor, Greg Abel, is investing his entire $15 million salary into Berkshire Hathaway stock. This is a powerful form of "eating your own dog food" that signals ultimate confidence in the company's future to the market, aligning his personal financial success directly with shareholder outcomes.

Insiders and CEOs are generally good at timing capital allocation, issuing shares when prices are high and buying back when low. The current lack of equity issuance from high-flying tech companies suggests their leadership doesn't view their stock as overvalued, despite having clear reasons to raise capital.

A tender offer, where a company buys a large block of its stock in a set price range, signals higher conviction than a typical buyback program. It forces management to put a stake in the ground, indicating they believe the shares are significantly undervalued at a specific price.
