Welcome to the Hot Corner Insider Weekly Report!

As you know, we spend a lot of time tracking insider activity to come up with this universe.

But that’s only half the battle!

Once we identify the names insiders are targeting, we overlay our expert technical analysis to see if the market agrees with their actions.

While we track some of the most powerful and well-informed market participants… we aren’t just going to follow them blindly into their trades.

We want to see that the insider activity is confirmed by the trend before we get involved. 

When we can check both boxes, we identify asymmetric risk/reward setups and then jump in and ride these trends higher alongside the smart money.

Warren Buffett’s Berkshire Hathaway just turned up the volume on its stake in Sirius XM Holdings $SIRI with the purchase of an additional 1,557,702 shares, valued at a cool $42 million.

Here’s The Hot Corner, with data from October 18, 2024:

The most significant insider activity today comes from Control Empresarial de Capitales S.A., the Mexican investment firm led by Carlos Slim.

According to a new Form 4 filing, the firm acquired 1,002,000 shares in PBF Energy $PBF, valued at $31.8 million.

This is Control Empresarial’s fourth major purchase in the last month, totaling nearly $55.9 million.

Today’s biggest insider move comes straight from John Edward Adent, CEO of Neogen Corp $NEOG. 

According to a fresh Form 4 filing, Adent just scooped up 14,500 NEOG shares, throwing down $200,000 in the process.

No one understands Neogen better than its CEO. And this wasn’t a pre-scheduled transaction or an option exercise – this was an open-market purchase.

CEOs don’t just throw six figures into their own stock for fun. They do it when they see real value. Adent sees upside in NEOG, and he’s putting his own cash on the line to back it up.

However, that doesn’t necessarily mean it’s time for us to jump in. As technicians, we only want to follow this insider data when the trend confirms it 

That’s not the case with $NEOG right now, as the stock is still in a downtrend. We will add it to our watchlist and be ready when the setup improves.
