How do call spreads and LEAPS work? A LEAP is a long-term option, one that expires longer than a year. (It's like the old warrants.) You're writing options against a position you have on a stock long-term. The return is better than if you held the stock. It's a good strategy.

Mutual funds vs. ETFs? Mutual funds have been closet indexers for a long time (which led to ETFs), because the large, diversified ones look like the broader economy. Unlike mutual funds, ETFs you can buy and sell on the market during the day, but with ETFs you don't always get the NAV, though this has improved. Mutual funds cost more than ETFs, so go for the lower cost.
What European ETF to buy? He suggest you put them in an RRSP, because you guy and hold them. The grandaddy is EFA-N. It's large, liquid and diversified. The Canadian version is XEF-T. Also look at XEH-T, which is purely Europe, though hedged to CAD. (Buy this if you think the CAD will rise against the Euro.)
Short put. Write a September $300 put. You're obligated to buy at the strike price. If it doesn't get down to $300, then the option expires worthless and keep the $22/share (it closed at $322 today). Put cash aside or have credit on the side to buy the to stock. This is way to play NFLX on a pullback.
