Results season is also the time that Chief Financial Officers and other C-Suite management resign, either because they were waiting out the clock till the end of the quarter, or because of missed targets, with quarter result numbers that their bosses are not happy about. Either way however, investors see big resignations like these - and their timing - not good news for companies. Some resignations over the past 24 hours:

• The CFO of fertilizer company Aries Agro has resigned. The firm is a majority family owned company, and investor Vijay Kedia held stock in the firm until June 2018. 
• CFO of CIMMCO has resigned. In CIMMCO's case the resignation may partly be an outcome of the company merger with parent firm Titagarh Wagons, although the cause has been publicly notified as 'personal'. 
• The CFO of pharma firm Piramal Phytocare has resigned, as has the CFO of Radha Madhav Corporation.

An auditor submitting a resignation letter while citing their "concerns" sends share prices spiralling down. However, a CFO’s exit can precede this and is a relatively early sign that some things are going financially wrong with a company - before a balance sheet reveals it. It's not the case every time, but if a company is already weakening, a CFO resignation is an additional red flag.
