Resistance Level

In technical analysis, a price that a security does not, or only rarely, rise above. Technical analysts identify a resistance level by looking at past performance. When the security approaches the resistance level, it is seen as an indication to sell the security, which will increase the supply, causing the security's price to fall back below the resistance level. If there are too many buyers, however, the security rises above the resistance level. When this occurs, the price of the security will likely continue to rise until it finds another resistance level. It is also called the overhead resistance level. See also: Price ceiling, Support (Support level).

Resistance, or resistance level, is the top of a stock's current trading range, and the point at which the price is higher than investors are willing to pay. As stockholders sell at resistance level, the stock price goes down because supply exceeds demand.

For example, if, on a repeated basis, as stock A's price reaches $60, stockholders begin to sell, then $60 is considered its resistance level. But a trading range isn't fixed and investor attitudes change, so the resistance level tends to move higher or lower over time.

If stock A rises to $63 without a surge of selling, the current resistance line has been breached. This may be the result of a rising market or a bullish assessment of the stock's value. On the other hand, if selling increases at $57, that may become the new resistance level.

Conversely, the level at which demand exceeds supply and investors typically buy a certain stock is called support. It's the point that's considered the bottom of a stock's current trading range.

Technical analysts use the concepts of resistance and support in anticipating future stock price movements.

Multivariate analysis of DGF incidence identified the following four significant risk factors: donor hypertension history, donor terminal sCr level, warm ischemic time, and terminal vascular resistance. HMP pressure and terminal flow did not significantly influence the rate of DGF, indicating that high pressure may not actually contribute to posttransplant renal dysfunction.
Ischemia might have augmented the release of vasodilatory factors, which might have decreased vascular resistance and increased blood flow.
However, contrary to this expectation, the decrease in the blood flow (Figure 2) and the increase in the vascular resistance (Figure 3) of the hepatic, small intestinal, and renal vascular beds due to hyperthermia were not seen under sevoflurane anesthesia, except 3% sevoflurane at over 40.0[degrees] C.
In this discussion, we characterize vascular function according to 3 criteria: (1) pulmonary vascular resistance; (2) pulmonary vascular compliance; and (3) acute vascular response to supplemental [O.sub.2] and/or iNO.

Mean values of renal RI and PI in dogs with HAC were significantly higher than those of healthy control dogs, suggesting that dogs with HAC experienced higher intrarenal vascular resistance [21].
[5] The critical factor determining prognosis in all the patients undergoing surgery is the degree to which the pulmonary vascular resistance is elevated before the surgery.
What's more, data from the -6[degrees] HDT experiment of the "Earth Star-1" project of China Astronaut Research and Training Center indicate that a sharp decrease of the lower venous compliance occurs, together with an increase of the total peripheral vascular resistance [40].
The following parameters were evaluated: peak systolic velocity (cm/s), end-diastolic velocity (cm/s), mean velocity (cm/s), pulsatility index, and vascular resistance index.
The possible mechanism responsible for the rightward shift of the chronic salt-loading pressure natriuresis curve in the uninephrectomized DOCA-salt hypertensive rats could be attributed to the increase in sodium reabsorption from renal tubules, or to the increase in renal vascular resistance.
