We are heading into the usual summer doldrums, and indicators are showing a lull in activity on the Hong Kong’s stock market. The two main liquidity gauges are starting to show signs of fatigue, while short selling is on the up and the number decliners is on the rise. Capital inflows have artificially lowered interest rates and are distorting the near term outlook. This should keep the index moving around the 18,300 fair value mark.
The first chart shows the rise and decline in recent weeks of stock market turnover and volume. The decline has been sharp and short. The second chart shows the money flow of the total market.

As turnover has dwindled, the index itself will start to oscillate less. The chart below shows the daily difference of the HS Index compared with its 21 day average. The straight line is two standard deviations of the average.

The z score indicator breeched two deviations at the March low and was one of the many signals of a cycle low. The peak in short selling in February also flagged the low. One reason why the Hang Seng Index has been so volatile on the downside recently was due to the lack of short sellers in the market. This situation suddenly changed last week as the chart below illustrates. The percentage of short selling jumped to over 8%.

So, who have left the market? Although the number of declining stocks is not necessarily an important indicator of activity, it is a good proxy for the nature of market participants. The recent surge in stocks that are declining on the Hong Kong stock market has been noticeable, with the daily tally getting into the 3,000 plus level on a regular basis. This is an indication that retail investors and small cap fund managers have exited the market. This has probably accounted for the decline in turnover and (in particular) volume, especially as the recent jump in IPOs and placements are high volume events.
HS Index and number of declining stocks

So what it causing: the decline in turnover, the rise in short selling and the increase in declining stocks? There is a large clue coming from the futures pits.
Since global interest rates have been declining, the HS Index futures contract has been trading at a discount to spot. This discount reflected the fact that the cost of borrowing on a levered futures contract has been all but zero. Prior to the emergency interest rate cuts of the past 18 months, futures contracts traded at a premium to reflect the cost of holding borrowed money. However, in the past two weeks, Hang Seng futures contracts (all months) have been trading at a small premium again. This reversal reflected an expected rise in local interest rates. At the moment, local interest rates and the HK$ are being kept artificially low/high by IPO and capital raising activities in the buoyant equity market. Also, demand for HK$ is always higher than usual at quarter end. But futures traders are wary of this and have been pricing in higher funding costs. The question that has changed the complexion of equity markets is whether, after the IPOs are complete and the quarter end passes, local interest rates will remain at current levels or will they spike higher. The prospect of permanently higher funding costs, albeit at still very low levels, is a new dynamic that local equity investors will need to navigate (it’s one of those items that makes the current bicycle different from previous cycles). While this question has no answer, equity prices (and their value relative to interest rates) will remain in a tight range, with short covering supporting the downside and the lack of retail buyers capping the upside.
