With the recent black-swan event that caused the entire world to literally and figuratively to be at an standstill, whether stocks are still considered "undervalued" using traditional metrics is an individual opinion. What I can advise, only invest monies that you are comfortable of locking-up long-term, it will be wise to buffer up your emergency funds esp in times like these before setting monies aside for investment

Too late to cry over spilled milk (stock positions that are currently in the red, you had the chance to offload some of those positions profitably over the last 2-3 weeks, but failed to do it). Just gotta comparmentalize those paper "losses" away & focus in rebuilding a stock porfolio bss on stocks that are going to be present great risk/reward proposition 10 years down the road

Financial engineering to create wealth effect

MapletreeNAC in the short-mid term prospects is damaged, if it is a small position, i would just leave it aside and just collect the dividends until the global equities market had truly weathered the virus situation then start averaging down.

Get a stock brokerage account that had access to US stock markets like nyse, ndq. Fund it with USD and you are good to go if are 18 years old

Newsflash, everywhere (even traditonal safe havens such as gold, jpy) is underperforming, STI is not the sole orphan in this equity meltdown. Since the bulk of your STI investment (alr in the red) in absolute amounts is not high, it made not much sense to realized your loss permanently, might as well let it be. In times of black swan events, sometimes its best to learn how to comparmentalize the spilled milk away. I would rather focus on building a new warchest and prudently deployed them over a one-year period on your shortlisted companies while being aware that lower lows is highly probable in the short-mid term horizon

" I am comfortable with it falling less than 10% after the purchase " - This coronavirus virus is an omega-level black swan. Volatility gonna be heightened over a downward trend the next few months at the very least as the World overall is still trying to grasp and contained the virus, with heavy supply disruption & demand destruction. If your heart can only withstand just a mere -10% drop in value, this current choppy markets is not for you. Of cos, as the good old Buffet adage goes, buy wonderful companies at a fair price. Well newsflash, even wonderful companies cannot survive extended periods without positive cashflows. Even an olympian level athlete, cant survive long without oxygen. And positive cash-flow is the oxygen for most/if not all companies (esp highly leveraged ones). When there's massive uncertainty on e 3 inputs used for any type of valuation growth rate, risk rate, current earnings for this year all at the same time, how does one with a certain confidence interval can conduct any discounted cash flow analysis. As such, other traditional metrics to value stocks such as price/earnings, price/book can be cast out of the window until normalcy return to market sentiment That said, our local banks are well-capitalized, and should survive & thrive 10 years down the road. But just because DBS can survived, its not a guranteed that price can rebound immediately/ quickly to previous pre-virus levels. Long term annualized return of a stock is a function of "entry price & time" Until, we see a peaked case of virus worldwide, should one decide to invest in DBS or any "good companies" out there, just rmb to rationed out your war-chest & netflix

All those foreign monies in foreign investments got to be sold and recalled back to US shores to offset their domestic US stock losses Even in the event that USA economy suffering, USD still the leading reserve currency to hide from falling knives

Take a look at Carnival Cruise Lines and US Airlines :)

The fact after 2 years of self-research, you still had to ask whether STI ETFs is worth it showed you had not made any substantial progress in your financial literacy and/or independence of thought in sieving and organizing various bits of information. Best move on to other stuff
