The three simulated portfolios set up to take some of the mystery out of investing took a hit last month. This is partly due to missing the boat on two bank shares.
DBS and UOB both shot up last month, but they were not represented in any of the simulated portfolios, which explains their relative decline against the benchmarks.
The Save & Invest Portfolio Series features communications manager Shona Chee, 26, entrepreneur Getty Goh, 39, who is married with two children, and retiree Wang Moo Kee, 63.
Introduced by The Sunday Times in January last year, the series does not involve actual money as it is intended for illustration and education only.
The portfolios are limited to instruments listed on the Singapore Exchange and the Singapore Savings Bonds. There are similarities between the holdings, but the allocations differ depending on individual risk-return objectives and preferences. Each portfolio has a benchmark that best reflects its mix.
Mr Goh's portfolio is heavier on blue-chip shares, while bonds fit Mr Wang's more conservative stance. The portfolios are constructed by the CFA Society Singapore (CFAS) for an ideal investment horizon of five to 10 years.
Ms Chee's portfolio dipped 0.76 per cent over the four weeks in the last month, trailing the benchmark by 1.85 percentage points.
Mr Goh's portfolio was down 0.7 per cent, 1.99 percentage points under the benchmark, while Mr Wang's took a 0.54 per cent dip, leaving it 1.47 percentage points below the benchmark.
The CFAS panel said: "Security selection across all categories explains the underperformance of the three portfolios compared with the benchmark.
"The Singapore equities allocation was dragged down by the sharp correction in Wing Tai, which fell 7.3 per cent, and their underweight position in banking stocks."
The panel noted that DBS stock was up 7.2 per cent for the month while UOB advanced 6.4 per cent but neither were in any of the portfolios. So these sizeable gains went begging.
It was the banking sector's rally last month that proved the main driver behind the Straits Times total return index's 1.9 per cent gain to 4,792.56 at the end of November.
There were other hitches as well.
The 0.7 per cent dip in A-Reit units pulled the Reit allocation below the broader S-Reit index, which was up 1.4 per cent.
The lack of exposure to United States equities and the 1.1 per cent correction in the greenback against the Singdollar explains why the global exchange-traded funds (ETFs) selection trailed MSCI World, which added 0.9 per cent.
The weakness in the US dollar, which hit the iShares JPM Asia Bond ETF, also explains the small underperformance of the bond allocation against the bond index, which rose 0.1 per cent.
There were no adjustments to the portfolios last month.
One of the more astounding successes of this year has been cryptocurrencies in general, and bitcoin in particular.
Bitcoin has risen more than 1,000 per cent this year and its market capitalisation now exceeds the gross domestic product of whole economies, said the panel.
Its run has all the makings of a bubble, with bitcoin fever infecting everyone from Wall Street to grandma on Main Street.
The announcement that bitcoin futures contracts will be on offer in the US - a move that suggests trading regulations will be brought to bear on the wild market - sent the currency surging 30 per cent in a week to US$11,434 (S$15,419) on Nov 29.
Shares had reason to prosper as well, with the new US tax Bill within sight and government regulations seen as hamstringing American business on track to be rolled back by the end of this year.
Data showing that the US economy in the third quarter grew at its fastest pace in three years added extra impetus to the rally.
The panel noted that the Dow Jones Industrial Average posted its biggest one-day gain in a year on Nov 30, closing above 24,000 for the first time.
Investors appear to have priced in the prospect of even-stronger corporate earnings next year with the proposed corporate tax cuts alleviating concerns of rising stock valuations.
The S&P 500 also broke records by logging its 13th straight month of gains, the longest streak in history. While this may be of concern, no obvious danger signals have appeared on the horizon as yet.
The party looks poised to continue as consumers welcome the holiday season with confidence at a 17-year high, as preliminary retail results for Black Friday reveal.
About US$9.6 billion has flowed into US-focused stock funds this year, helping to push net flows into positive territory, said Morningstar. The Dow Jones Industrial Average is up 22.14 per cent, the S&P 500 ahead 17.59 per cent while the Nasdaq has added 27.34 per cent.
Singapore registered its fastest growth since the end of 2013, with an expansion of 5.2 per cent in the third quarter compared with the same corresponding period last year.
This prompted the Ministry of Trade and Industry to upgrade its full-year growth forecast for this year from 2 to 3 per cent to 3 to 3.5 per cent.
