What type of bias is this?

2008 AM

“I am holding a large position in Omega Corporation with a large unrealized loss.
Omega’s stock price declined last year when reported sales and earnings failed to meet
analyst expectations. I took advantage of the decline to increase my position. Omega
sales growth has continued to slow over the last year, but I believe the stock is still a
good investment.”

You’ve made it this far, and you know what it takes to pass. Don’t be fooled by false promises and unrealistic claims. Schweser’s CFA® study packages give you the proven study tools and expert instruction you need to finish the job.

Loss aversion.

It was a long shot, glad i made it.

Answer is Regret Avoidance. No idea if that’s the 2008 equivalent of Loss Aversion.

Were there choices of biases in the question format? Could be regret avoidance because of the fear of missing out on the increase once the stock turns around, but i still think it’s heavy on loss aversion by increasing his position.

Not sure

It was a long shot, glad i made it.

I would have went with loss aversion here too 

Looks like a little of both loss aversion and regret aversion. The first part points to loss aversion (holding onto loses abd buying more) but the 2nd part points to regret (regretting that if he doesnt double down and the stock rises back in value, he would be kicking himself)

If you increased your position when prices fell it is not loss aversion. With loss aversion you would just hold it and hope it reverts back.

I would have gone with regret aversion. Regret aversion usually gets you to do something (afraid that if you don’t do you are left out from a big gain) while i loss aversion you don’t do anything just wait.

I agree with Moosey - loss aversion as far as I know does not include increase in position.

Overconfidence

Because of the ambiguity in the biases, CFAI now always gives the set of biases to choose from. Are there any choices? To me, it looks Overconfidence. 

No choices.
Overconfidence was already the obvious answer in another part of this question (and can’t choose one for multiple answers).

You and me both cause he’s confident it will perform well and that’s why he’s buying more.

My two cents :

Overconfidence.

Loss Aversion : No. Because the investor is constantly buying at every dip. Loss Aversion will dictate holding not adding position

Regret Aversion : Most certainly not. Regret Aversion is stemmed from the fear of therory of commission vs. therory of omission. Either one will manifest. In case the whole market we’re buying at dip the investor will follow the suit and not take CONTRARY action. Herding behavior. Else, he would do nothing and sit tight for the fear of losing when the stock rises.

back against the wall. no retreat no surrender.
