RED Flag found on Chip Eng Seng

I had made about 19% profit in 2018 for holding for 5mnths since late 2017. Now that I am looking at it, thinking of jumping back in. BUT there is RED FLAG that did not materialize in 2017.

Operating cash flow is negative for the last 3 years, 4 out of last 5 years. Debt/Equity ballooned to 220%, Finance cost/Interest is 50million. Segment wise, education is in red, construction is in red, hospitality as glamour as it seem is in red but chuck out a tiny cashflow after adding back non cash items.
 
Those invested please DYODD. Don't be stuck in another Hyflux. This one is really bad! Better safe than sorry
