{"product_id":"stcov253prpr","title":"Stocks \u0026 Commodities V. 25:7 (36-39): Premarket Prediction by Victoria Wang","description":"Premarket Prediction by Victoria Wang\u003cbr\u003e\u003cbr\u003eCan premarket activity be a\npowerful predictor as to how\nunderlying stocks will perform\nduring regular market hours? Will\nthis knowledge be advantageous\nto traders?\u003cbr\u003e\u003cbr\u003ePremarket activity\nrefers to stocks that\nundergo active trading\nbefore the US\nmarket opens \nthat is, before 9:30 ET. This activity may be caused by\nearning announcements from either\nbefore the market opens or\nafter yesterdays close, upgrading\nor downgrading by analysts, or\nother news that may influence the\nstocks movement. After analyzing\nabout a half-years data, we\nare beginning to uncover the connections\nbetween premarket activity\nand stock trends during regular\ntrading hours.\u003cbr\u003e\u003cbr\u003eDATA COLLECTION\u003cbr\u003e\u003cbr\u003eThe first step in the analysis is\ndata collection. The premarket\ndata was collected from the\nNASDAQ website from February\n1, 2006, to July 31, 2006. We\nwrote a program that fetched the\ndata from the website every\nmorning around 9:25 ET. This\ndata includes the current price\nbefore the market opens,\nyesterdays closing price, and\nthe premarket trading volume.\nUsing this data, we were able to calculate the percentage change of the current price relative\nto yesterdays close, referred to as percent change.\nWe will discuss the effects of these data on the underlying\nstocks movements during regular trading hours. Trading\nactivity involves entering a position at the open price and\nexiting the position at the close of the day; therefore, this is a daytrading system. For short positions, we are limited\nto stocks with a price above $6.","brand":"store-traders-com","offers":[{"title":"Default Title","offer_id":52133976637809,"sku":"\\V25\\C07\\133WANG.PDF","price":2.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0900\/3843\/6209\/files\/unnamed_8ce53ef2-3574-4656-8d6f-7a099c4bdabd.jpg?v=1739659957","url":"https:\/\/shop.traders.com\/products\/stcov253prpr","provider":"Stocks \u0026 Commodities","version":"1.0","type":"link"}
