Well, @harpreethwalia, there is bad news and good news.
The bad news is that no one can predict the future. Or at least if there is anyone who can predict the future they are using their skill to make themselves rich; they are not giving this information away for free on the internet. The consequence of this is that any recommendations you get for specific proportions and sectors are nothing but guesses and worth only the (zero) price you pay for them.
The good news is that the only proven winning strategy is passive investing -- buy everything and ride the wave of international productivity increases expecting a long term average growth of your (equity) investments at maybe 5-8% per year. This is an almost hands-off strategy. My wife and I look seriously at our portfolio only once a year and then we often make no adjustments.
So then the question becomes "What is 'everything?' " Most US investors have significant home country bias in their portfolios, as Kenneth French discusses. This has actually been advantageous over the last 10 years or so as the US market has outperformed the ROW (rest of the world) markets. But no one could have predicted this and no one knows whether it will continue. There is a concept called "Reversion to the Mean" that argues that it will not:
https://en.wikipedia.org/wiki/Mean_reversion_(finance) For my wife and I, "everything" really means "everything" as in VTWSX and VT. I think this is a somewhat unusual position, however, even though the statistical data IMO supports it.
So, more bad news: You will have to determine for yourself how much, if any, home country bias you want to have. Watch that Kenneth French video carefully and repeatedly; that will hellp. Note too, that right at the end, French admits to some home country bias in his personal portfolio even though he has just spent his time arguing against it.
Yes, but you must plan to be absolutely stalwart in holding your equities regardless of market gyrations. If you panic and start trying to time the market, history says you will lose big time.
I am not a Fido expert but last time I checked they did not have a world stock fund. You can get very close, however, with a 45% position in a US total market fund and 55% position in an international total market fund. If you're fastidious, you might want to adjust the proportion once a year or so to reflect market action.
(Note: Funds like an S&P 500 fund or an EAFE fund are not "total market.")
Sorry, no magic bullets. HTH
