My StashAway Simple generating interest steadily but Syfe Cash+ is generating a negative return?

Both of them invest in money market funds which experience very slight volatility in returns. Also they are quite different from an FD in that they are not SDIC insured. By extension, neither your returns (nor your capital) are guaranteed

You need to be patient my friend. You cannot be opening your app every day or week to look at how much you have gained.

This is a mid term to long term investment horizon. Manage your expectations and learn to park your money here while you sleep or do other more important stuffs in your life.

This is cash management not fixed deposits.
Once you understood this product further, either you keep all your principal sum into Syfe Cash+ or into Stashaway Simple. Don't do both. Maximise your returns in one.

It isn't like a Fixed Deposit. When starting out with different instruments, it is good to understand whats the funds that you're investing in your investment goal. In the short run, fluctuations is unavoidable. Always put your perspective in the long term.

Disclaimer, not my reply, but I got an email from Syfe on the lately dip on Cash+. Thumbs up on their end to educate users (but you also need to do your due diligence). In short, yes don't treat your investment as a day to day gamble, see the long term horizon and understand the market sentiment.

Over the past three trading days (12 to 14 April), Cash+ has seen a drawdown of 0.18%. The volatility in recent days has primarily been caused by corporate bond exposures within the LionGlobal Short Duration Bond Fund. 

We are in close touch with LionGlobal and the fund managers. While periods of modest volatility are to be expected, the chances of sustained or permanent losses are low given that the underlying investments of Cash+ are high-quality bonds.

As a reminder, while Cash+ is a low-risk product, it is not risk-free. To earn an enhanced return above bank deposit rates, the underlying funds are exposed to government bonds, commercial bills and high-quality corporate bonds which are traded daily and therefore subject to market volatility.

For example, between the launch of Cash+ and 31 March 2021, there were 15 out of 57 trading days where the daily return was negative. In all but one of these cases, the negative return was offset by positive returns within three days, and in one case the total return was positive again within two weeks.

Going further back, during the extreme market volatility of early 2020, our historical backtesting shows that the Cash+ portfolio would have experienced a peak to trough drawdown of -0.82% during March and April 2020.  This loss was fully recovered by the end of May 2020, and the return for the full-year 2020 was +2.72%.

In summary, we have constructed Cash+ with a modest amount of risk exposure in order to provide investors with an enhanced return above bank deposit rates.  

From time to time, there will be periods of modest drawdown, as we are experiencing now.  We encourage investors to be patient and not to make rash decisions during these periods.  Historical returns show us that as long as investors have a slightly longer time horizon (3 - 6 months and longer), they should be rewarded with a positive return and a yield premium above capital guaranteed alternatives.
