Four shares that have fallen more than most today are listed below. Here's why they have started the week in the red:

No reason was given for the sale.
The REA Group Limited (ASX: REA) share price is down almost 5% to $75.73. With no news out of the property listings company, today's decline could be down to weak housing market data.

The Vocus Group Ltd (ASX: VOC) share price is down 3% to $3.53 after media speculation of an upcoming equity raise. The telco company has responded to the speculation this morning, advising that its board and management remain comfortable with its debt position. As such, there is no current intention to raise additional equity.
The Wattle Health Australia Ltd (ASX: WHA) share price has tumbled 3.5% to 83 cents despite there being no news out of the infant formula and baby food company. At one stage today the company's shares hit a 52-week low of 80 cents. Investors appear to be losing patience with Wattle Health after its sales growth in the first half underwhelmed. Last month the company delivered first half revenue of just $363,000 and a sizeable net loss of $4.3 million.
