DJIA equal weighted kalo SPX (S&P) tidak equal weighted (weighted average) Nasdaq - weighted average jadi hanya DJIA aja yang metode nya berbeda
_____ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Wiro Milis Sent: 30 Agustus 2008 5:54 To: [email protected] Subject: Re: [saham] Basic Fundamental Dear Pak Sudes, Setahu saya DJIA tidak equal weighted kok? SPX (S&P500) juga tidak equal weighted. Karena penasaran saya coba googling ini dari wikipedia: http://en.wikipedia <http://en.wikipedia.org/wiki/Dow_Jones_Industrial_Average> .org/wiki/Dow_Jones_Industrial_Average Additionally, the DJIA is criticized for being a price-weighted <http://en.wikipedia.org/wiki/Price-weighted> average, which gives relatively higher-priced stocks more influence over the average than their lower-priced counterparts. For example, a $1 increase in a lower-priced stock can be negated by a $1 decrease in a much higher-priced stock, even though the first stock experienced a larger percentage change. As of November 2007 <http://en.wikipedia.org/wiki/As_of_November_2007> IBM <http://en.wikipedia.org/wiki/IBM> is the highest priced stock in the index and therefore has the greatest influence on it. Many critics of the DJIA recommend the float-adjusted market-value weighted S <http://en.wikipedia.org/wiki/S%26P_500> &P 500 or the Dow Jones Wilshire 5000 <http://en.wikipedia.org/wiki/Wilshire_5000> , the latter of which includes all U.S. securities with readily available prices, as better indicators of the U.S. market. Jadi bisa saja 10 component (saham) weighted teratas dalam DJIA naik, 20 lainnya turun dan DJIA masih positif. Makanya saya sering bilang: external index kyk DJIA sering kali paint a wrong picture. Mungkin Pak Sudes bisa konfirmasi lebih lanjut mengenai hal ini. Terima kasih and best regards, Wiro. 2008/8/29 Samuel Sudeswanto Yeung <samsudesyang@ <mailto:[EMAIL PROTECTED]> sinarmassekuritas.co.id> Dow Jones Industrial Average ("DJIA") dibentuk berdasarkan metode rata-rata aritmatik dimana setiap emiten yang termasuk didalam index tersebut memiliki bobot yang sama walaupun setiap emiten yang ada memiliki nilai kapitalisasi yang berbeda-beda. Kenaikan/penurunan index berdasarkan besaran kenaikan/penurunan dari saham-saham yang terdaftar dalam index tersebut.
