What this transaction means for investors
There are many reasons an insider may sell shares in a company. One reason could be the need to raise cash to fund a large personal expense. Another reason could be for a reasonable portfolio diversification unrelated to their outlook for the company. A third reason could be what investors fear most: a bearish outlook on the company's future.
However, there is only one reason an insider buys stock: they believe the share price is going up.
By that rule of thumb, Bertarelli's massive purchase is bullish. Helping the bull case: more often than not, an insider purchase predicts a higher share price 30 days later.
The Swiss billionaire, whose net worth is estimated by Forbes to be about $12 billion, has doubled down on his huge investment into Madison Air Solutions with this purchase.
MAIR has only been public since April, when it helds it initial public offering at $27 a share. The stock has seen typical post-IPO volatility, rising and then recently falling below the IPO price. Bertarelli stepping in with this massive private placement is the billionaire telling the world he believes in MAIR long-term.
Revenue for MAIR is seen growing 18% to $3.9 billion in the current fiscal year, with net income of $347 million and free cash flow of nearly $500 million. The business outlook is good. Combined with Bertarelli's most recent $200 million commitment, it's a signal for investors to buy MAIR.
