Not surprisingly, the recent insider buying spotlight is on Elon Musk’s billion-dollar purchase. But he wasn’t the only insider to boost a stake in the past week or so. A renowned precious metals investor made a sizable purchase as well, and the biopharmaceutical industry was well represented among recent buys.

Let’s take a quick look at these notable transactions in the past couple of weeks.

Is Insider Buying Important?

What does insider buying tell us?

A well-known adage reminds us that corporate insiders and 10% owners really only buy shares of a company because they believe the stock price will rise and they want to profit from it. Thus, insider buying can be an encouraging signal for potential investors. This is all the more so during times of uncertainty in the markets, and even when markets are near all-time highs.

With the second-quarter earnings-reporting season over, insiders are largely free to buy or sell shares until the next season begins. Below are some of the most notable insider purchases that were reported recently, starting with the largest and most prominent.

Tesla

  • Buyer(s): CEO Elon Musk
  • Total shares: more than 2.5 million
  • Price per share: $371.38 to $396.54
  • Total cost: about $1.0 billion

This was Musk’s first major open-market buy in recent years, and it is being widely interpreted as a strong vote of confidence in Tesla Inc. (NASDAQ: TSLA). Also garnering a great deal of attention is a proposed new pay package for Musk that is potentially worth up to $1 trillion.

The stock is up 25.6% in the past month and is trading near an all-time high of $488.54. The share price is 81.8% higher than a year ago, far outperforming the S&P 500. The stock has well outrun the analysts’ $320.71 consensus price target. And fewer than half of the 45 analysts who cover the shares recommend buying them.

Note that the EV maker’s CFO and another executive sold some shares recently.

CG Oncology

  • Buyer(s): a director
  • Total shares: more than 1.5 million
  • Price per share: $33.00
  • Total cost: about $50.0 million

CG Oncology Inc. (NASDAQ: CGON) is a California-based biotech focused on treatment of bladder cancer. Last month, it reported positive clinical data and quarterly results. The share price is 40.3% higher than a month ago but up just 3.8% year over year. Shares were last seen about $3 higher than the buyer’s price. Analysts see plenty of room for the stock to run, given their $59.73 consensus price target. All 12 analysts who cover the stock recommend buying shares.

Here too, a few other insiders have been selling shares lately.

Hycroft Mining

  • Buyer(s): 10% owner Eric Sprott
  • Total shares: over 9.3 million
  • Price per share: $4.28
  • Total cost: nearly $40.0 million

This transaction was a private placement and lifts Sprott’s Hycroft Mining Holding Corp. (NASDAQ: HYMC) stake to more than 17.5 million shares, or approximately 33% of the stock. He also made a sizable purchase back in June, when the chief executive and other officers were selling shares.

The stock is up 180.5% since the beginning of the year, including an 8.4% pop in the past week to well above the purchase price above. Only one analyst covers the stock and has a Hold rating with no target price.
