Types of Trend
Uptrend
It is the trend when financial demands and assets move in upward directions, increasing the price. It is usually the time of the explosion in the economy, where overall beliefs are favourable.
Downtrend
In the downtrend or the bear market, the frugality, financial markets, and assets prices stride in the downward direction. It is the time when companies decrease operations and overall investor sentiment is not positive.
Sideways / horizontal Trend
In this, the bargains prices or the broader economy-level are not moving in any way, rather are moving sideways. This means, holding up for some time and then down on the same level. It is a risky activity as investors are hesitant of what will happen to their enterprise.
Disadvantage
One major drawback of trend analysis is that it is not 100% accurate. Or, we can say ahead behaviour is not always indicative of fortune. This is because various factors affect the price of safety (or revenue and expense), and these characteristics change over the period. Also, critics of such a technique argue that markets are profitable, and the stock price already reflects all accessible information. This means that the past won’t repeat itself. Thus, it is always advisable that one must fund technical analysis with substantial research to make a decent prediction.
