no need. being 35years old and living mortgage free for about 4 years now is nice. plus my income properties pay my rest of bills and taxes. I play with extra money and spend extra money . only a insane person would take a loan on their house. I am a huge fan of titan specially of lately. participated in latest offering . it will be fine . had my share of wins and losses .
There is apposite symmetric thing you can do. There is no one that can stop anyone borrowing money against their house and shorting any stock that they want inclusive of Titan and the risk is in fact massively more in that scenario because the losses will not be limited to invested cash.
