The Australian S& P/ASX 200 index and the Singapore Straits Times index have both entered overbought territory. Although as of the close of Friday both indices were up substantially on a YTD basis,  2-year returns  are still negative. The probability of a correction during next week is high at this point.
 
On the above chart, the top pane shows daily prices of the S& P/ASX 200 index for the last two years and the pane below it the RSI(14) values.  It may be seen that this indicator is now at levels that when reached in the past (vertical markers) signalled the beginning of a significant correction. This does not mean that necessarily the same will occur this time around but it is good to know that and be prepared just in case.
The bottom two panes show the YTD and 2-year returns of the S& P/ASX 200 index. It may be seen that although the YTD return is near 14%, the 2-year return is still negative. Thus, although the index covered a lot of room in 2012,  it has not managed to recover 2011 losses.
The Straits Times index is also overbought and about 20 points away from its August 1, 2011 high. The RSI(14) is at 77.5 having reached a high of 81.23 last week. Although the YTD gains are impressive at 18.73%, also in this case the 2-year return is negative at -1.8%.  By contrast, the 2-year return of S& P 500 is 10.41% one trading day before the end of the year. Thus, what some analysts label as a spectacular performance of this index during this year must  be  evaluated from the perspective of a recovery of losses  from the previous year.
