險中求勝 (2007/8/24)
網友yuki問了一系問題,其中大部份本來都是我想講的入市時要思考的問題,可以綜合講講。
她問:「Luk Sir:The liquidity injection is up to USD172.5億 last night. Do you think the recent crisis is still very serious?
Do you think we can still take the strategy as before, i.e. buying non-leading stocks and holding them? The risk concerned is when great correction occurs, even they have not rebound yet, and they will also fall drastically with the market.
Seeing the small priced stock being active again. Do you think it is time to make short term strategy to speculate them?
Do you think being a 好友 in long term always win? When the market performs well, the central banks do nothing to prevent it being too hot, except the Chinese one. However, when there is serious downturn, the central banks use all measures to help build up the public’s confidence.
I do know the mechanism of straddle and strangle and under what circumstance investors should use it. However, I think there are implementation problems. The cost of using option or futures is too high. If use calls and puts, the effect would be affected on the choice of warrants. Sometimes, the issuers may quote the bid and ask price too wide, the premium may be too expensive to make the strategy not profitable. Can you further explain how to choose the suitable warrant to give a better return, apart from similar expiry date, the conversion price?
You give us an example some days again, i.e. 19800 put and 23400 call which is 1800 points from 21600. That means we need the HSI goes up or down more than 1800 to make it profitable. I am wondering why we don’t us small difference, say 1000 instead of 1800 to make the strategy more easily profitable?」(對不懂英文的朋友,我暫不翻譯,住下會逐一重覆問題)
網友如果是投資者(不是投機者),會被近日的股市嚇親,初時不信嗰市會升得咁快,繼而抱怨,再感無奈,最後會相信,但會怨句信得太遲,甚至衰起上來一開始信佢去入市,佢又回吐,即時中一棍。
投資者會比較遲疑,投機者會搶先,大市初定,炒作香港大市的大戶,便搶先入市,次次都係咁,你未睇定時,佢已把大市搶高,今次所不同的是他們手法更狼,目前已搶過上月期指結算時大市的水平(22700點),更令我懷疑佢地大量好倉主力未平倉,所以外圍局勢初定,佢立刻全面發難,根本唔俾淡友有任何機會反攻。
你問外圍大勢,仍在刧後穩定中,所以美國聯儲局仍在放水中,但大勢已趨穩,日本央行決定不加息,日圓一度跌番去117水平,套息交易又在日圓高位開倉(紐元現價0.717美仙左右,8.25厘息,半年中期投資有吸引力),次按的問題本質其實好嚴重,商業票據市場目前仍然死咗,但在聯儲局發功放水下,應該又可以把問題冧住,等個鑊慢慢爆。大市當然有風險,目前去買,是險中求勝。
你問好友是否長勝,從一個三、五十年的角度,在一個增長中的經濟,做好友,買佢嗰股市整體向上,道理似乎啱。但從一個兩、三年投資的角度,雖然一跌央行就會干預,但資金泛濫到咁上下,資產泡沫吹到咁上下,就有一爆,那種爆法係央行都頂唔到,二000年科網潮爆破,就是一例,你高位28元買了電盈(0008),現價撇除股份五合一的效應,1元都唔夠,你話好友一定贏,又唔係噃,當然要睇你乜位入,買乜股。
在次按危機和大陸資金自由行一好一淡消息影響下,兩個都係巨大的利好或利淡消息,我傾向睇好港股後市,認為要對港股、甚至香港整個投資市場再評價(我會在周一頭條日報專欄再論述)。
短期紅色指數股超買,高追有風險,但大把股票好落後,好多二、三線的股票,例如二、三線大陸地產股,若大市向好,它們還有好多水位。Yuki問追這種落後股,雖然升咗唔多,但若果再大跌時,會唔會都跌好多。我認為你首先要對大市中線(三到五個月)有個看法,若睇好,可以追;若睇淡,認為港股未跌完,當然唔好追。
至於雞股,道理亦一樣,雖然我唔會叫人買雞股,但若你有買開雞股,低位放咗,好多而家只是升番少少,未大郁,但如果大市向好,過兩三個月,莊家又會再炒過,所以也是睇大市,買唔買就要你自己判斷了。
另外有關馬鞍式窩輪的策略,下星期一再談。
