The first link is a FB page I follow has some very useful articles and is updated regularly, I found the link 3 from the page.
My aim here is to advice all the investors who are worried about the market dropping and loosing their hard earned money. I know it's not easy but hang in there. refer link 2 this is not the first time the market has dropped like this it has happened in the past. People who invested during those times benefited immensely when the market went up. As the famous investor said it ' Be Fearful When Others Are Greedy and Greedy When Others Are Fearful” Warren Buffett.
Link 3 is the forecast done by a brokerage firm and they have raised the corporate earnings forecast so good times ahead. Hope this is useful.
