What this transaction means for investors

Mantarro has spent a remarkable 43 years at Banco Bradesco, where she is now the global head of internal audit. Odds are she really knows what is going on deep within the bank's financials. That she is buying is a bullish sign.

That's because there are many reasons an insider may sell a company's shares. 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.

But there is only one reason an insider buys stock: they believe the share price is going up.

By that investor's rule of thumb alone, Mantarro's million-dollar-plus purchase of Bradesco shares is a bullish signal. That signal is further bolstered by studies showing that, more often than not, an insider purchase predicts a higher share price 30 days later.

This shows signs of being an insider-buying-low transaction. That's because high credit costs in Brazil, combined with poor loan growth and net interest margin compression, led to a sharp decrease in earnings in the past. Banco Bradesco's results have been recovering since then, but the bank has to show that its operational issues have been solved before Wall Street piles into shares.

That said, over the past year, the Brazilian economic environment for consumers has improved, Bradesco is seeing operational and financial improvements, and inflation is moderating, mitigating risks.

Insider buying like Mantarro (and she is one of just a big slate of Bradesco insiders buying of late) coupled with a positive fundamental story increase the odds of making a profitable investment decision.
